i cant install in laravel 5.8
how to resolve this problem?

Problem 1
    - Root composer.json requires victorybiz/laravel-tel-input ^1.2 -> satisfiable by victorybiz/laravel-tel-input[v1.2.0].
    - victorybiz/laravel-tel-input v1.2.0 requires illuminate/support ^8.0|^9.0 -> found illuminate/support[v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev] but these were not loaded, likely because it conflicts with another require.
  Problem 2
    - orchestra/testbench 6.x-dev requires mockery/mockery ^1.4.4 -> found mockery/mockery[dev-master, 1.4.4, 1.4.x-dev (alias of dev-master), 1.5.0] but the package is fixed to 1.3.5 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - orchestra/testbench[v6.0.0, ..., v6.7.0] require laravel/framework ^8.0 -> found laravel/framework[v8.0.0, ..., 8.x-dev] but it conflicts with your root composer.json require (5.8.*).
